-159 BROWN FKM 75D O-RING

VB75159 is an AS568-159 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 4.987 in (126.67 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.193 in (131.9 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists aromatic hydrocarbons, chlorinated solvents, and petroleum oils and fuels. Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

Typical settings include automotive fuel systems, oil and gas, and semiconductor equipment.

Order part number VB75159, sold individually. Unit weight is approximately 4.7125 g and nominal inside diameter is listed as 5 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
